7.1.安装dashboard WEB控制台

1）安装dashboard软件包

yum install openstack-dashboard -y

2）修改配置文件/etc/openstack-dashboard/local_settings

# 检查确认有以下配置

vim /etc/openstack-dashboard/local_settings

-------------------------------------

ALLOWED_HOSTS = ['*', ]

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

OPENSTACK_API_VERSIONS = {

    "identity": 3,

    "image": 2,

    "volume": 2,

}

OPENSTACK_HOST = "controller"

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"

CACHES = {

    'default': {

         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',

         'LOCATION': 'controller:11211',

    }

}

OPENSTACK_NEUTRON_NETWORK = {

    'enable_router': False,

    'enable_quotas': False,

    'enable_distributed_router': False,

    'enable_ha_router': False,

    'enable_fip_topology_check': False,

    'enable_lb': False,

    'enable_firewall': False,

    'enable_vpn': False,

}

TIME_ZONE = "Asia/Shanghai"

--------------------------------------

# 配置选项：

配置dashboard运行在192.168.1.81上（192.168.1.81为OS主机名）

配置允许登陆dashboard的主机

配置memcached存储服务

启用第3版认证API

启用对域的支持

配置API版本

通过仪表盘创建用户时的默认域配置为 default

通过仪表盘创建的用户默认角色配置为 user

如果您选择网络参数1，禁用支持3层网络服务：

可以选择性地配置时区，不能用CST否则无法启动httpd服务

3）修改/etc/httpd/conf.d/openstack-dashboard.conf

# 增加以下内容

vim /etc/httpd/conf.d/openstack-dashboard.conf

-------------------------------------

WSGIApplicationGroup %{GLOBAL}

-------------------------------------

4）重启web服务器以及会话存储服务

systemctl restart httpd.service memcached.service

systemctl status httpd.service memcached.service

5）检查dashboard是否可用

# 在浏览器中输入下面的地址：用户名和密码都是admin，域名用default

http://controller:80/dashboard

# 浏览器页面如下：

# 登录后显示这样一个摘要信息：

# 新安装的默认里面基本是空的，需要后续手动添加扩充

6）其他可选的dashboard配置
